M50 (New York City bus)

The M50 is a public transit line in Manhattan, running primarily along 49th and 50th Streets in Midtown Manhattan. Originally a private bus line started by Green Bus Lines in 1933, it is currently operated by the MTA Regional Bus Operations under the New York City Transit Authority brand.

Route description
The M50 begins at Pier 83 on the West Side, traveling north along 12th Avenue before running east along 50th Street to Second Avenue, where it transitions via Second Avenue to running on 48th Street to First Avenue before making two consecutive left turns onto 49th Street, where it terminates. The M50 westbound routing is the same as the eastbound routing, except that it uses 49th Street instead between First and Twelfth Avenues.

History
In 1933, Green Bus Lines had initially received one-year franchises to operate six Manhattan crosstown bus routes, one of which was the M3. In 1935, the M3 was transferred to the Comprehensive Omnibus Corporation and once again transferred to New York City Omnibus Corporation in 1936. On July 1, 1974, the M3 was relabeled to the M27. Circa 1989, the M27 became a part of the M50, which ran to Pier 83. On June 27, 2010, due to budget shortfalls within the MTA, the M27 was eliminated and M50 weekend service was discontinued. These changes were expected to save $1,900,000 annually, although weekend service on the M50 brought back in exchange for truncating the eastern end of the route to 49th Street from United Nations on July 3, 2011.
